After installing apache in CentOS it would go to Apache 2 Test Page.

To locate this directory you need to go to /var/www/
In this directory you can create your file which you needs to run.

To set up Virtual Host navigate to /etc/httpd/conf/httpd.conf file

Open the file in gedit or editor of your preference.

Add the lines below

<VirtualHost *:80>
   DocumentRoot /var/www/sample/
   ServerName virtualhost1

The document root points out to sample older in www directory

The server name is virtual host name you type in URL
